Thank you so much for your attention.Actually my questions are: 1.std.date has no implementation on getting local region system time,is this true?Say getUTCtime(),UTCtoLocalTime() are all 8 hours behind my region;I remembered in Tango this is not a problem.gtkD provide a clock demo which I have build both under D1+tango and D2,2 exe show different time.The tango one is correct. 2.If I want to get proper system time under D2,I need do by myself,either +8hours hard-codes or call system API by myself,is this the only choice? Thanks and best regards, Sam

Ah, I see, thanks. But choosing an insane big number of precision in combination with g seems to work perfectly already. Although there probably is a better formatting option, I hope.

I found the formatting options, they are in std.format..

Is linked able to optimize them out? No, the DMD linker isn't smart enough. (Maybe the LDC one is?) BTW that's why D2 has 'enum' for manifest constants. It's a language hack to work around a linker limitation.
